Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This application claims priority to Taiwanese Patent
Application No. 101113793, filed Apr. 18, 2012, which is hereby
incorporated by reference.
FIELD OF THE INVENTION
[0002] The present invention relates to a method of zooming an
image of a touch device, and more particularly to a controlling
method for fixing a scale ratio of browsing images of a touch
device.
BACKGROUND OF THE INVENTION
[0003] With the rapid progress of science and technology,
electronic products, such as the tablet PC and the cell phone which
are light, thin, small, and portable, have been developed to
provide much convenience to people and improve the life quality.
Most of the electronic products are equipped with an input device
for inputting information, for example, a mouse or a keyboard, but
such input devices are not thin and simplicity. As the result, new
generation of input devices, such as a touch panel, are provided
and have been applied to various electronic devices. In a touch
panel, there is provided with a touching region that corresponds to
a displaying region, so that a user can control the electronic
products by sliding or touching icons that is displayed on the
touch panel to execute the corresponding function.
[0004] The size of touch panel of an electronic product is always
limited, and therefore it is inconvenient to show all icons of the
touch panel.
[0005] In the electronic product, it generally provides a zooming
function for zooming in/out an image to a desired scale. In a
general image zooming method, a user selects a region of the panel
that is to be zoomed at first, and the user determine to zoom in or
zoom out for the selected region, and finally the user determines a
scale of zooming ratio or a defaulted scale of zooming ratio is
applied.
[0006] However, the above image zooming method has drawback as
follows. One of the problems is that the procedure of operation is
complicated, which includes a step that a user has to select the
region to be zoomed, a step that a user has to choose either zoom
in or zoom out function for the selected region, and a step that a
user should select the scale ratio for zoom in or zoom out
function. Besides, in the conventional method of locking a region
of the touching device, the device generate a block on the
displaying panel, and a user "drag" or "align" the block to
determine the region to be locked. The conventional method is
inconvenient.
SUMMARY OF THE INVENTION
[0007] Accordingly, the present invention provides a controlling
method for fixing a scale ratio of browsing images of a touch
device to improve the drawback of conventional touch device when
the zooming is operated.

performs a displaying area control of a browsing image shown on a
display screen, the controlling method comprises the steps of: (a)
determining a zooming region on a display screen, which is
determined by pinching the browsing image from a selected position
to thus zoom in or zoom out the browsing image, and the scale ratio
of zooming is accordingly determined; (b) displaying a
screen-locking icon on the display screen, wherein the scale ratio
is locked when the screen-locking icon is triggered to be in a
locking state; and (c) displaying the other browsing images with
the same scale ratio of zooming and with a viewing size same as the
zooming region.
[0009] In another aspect of the present invention, it further
comprises a step (d), after the step (c), of restoring the scale
ratio of the present browsing image to an original scale ratio when
the screen-locking icon is triggered to be in an unlocking
state.
[0010] In another aspect of the present invention, wherein the
scale ratio of the other browsing images is restored to the
original scale ratio when the screen-locking icon is triggered to
be in an unlocking state.
[0011] In another aspect of the present invention, wherein in step
(a), the zooming region is determined by pinching the browsing
image from the selected position and extending outward to enlarge
the scale ratio of zooming, and the scale ratio of zooming is thus
determined.
[0012] In another aspect of the present invention, wherein in step
(a), the zooming region is determined by pinching the browsing
image from the selected position and extending inward to minify the
scale ratio of zooming, and the scale ratio of zooming is thus
determined.
[0013] In another aspect of the present invention, wherein the
browsing image on the touch device contains one or more of text,
graph, symbol, and video.
[0014] In another aspect of the present invention, it further

BRIEF DESCRIPTION OF THE DRAWINGS
[0017] The structure and the technical means adopted by the present
invention to achieve the above and other objects can be best
understood by referring to the following detailed description of
the preferred embodiments and the accompanying drawings.
[0018] FIG. 1 is a flowchart illustrating the controlling method
for fixing browsing image to zoomed region of touch device of the
embodiment according to the present invention; and
[0019] FIG. 2 to FIG. 6 are operating schematic diagrams
illustrating the controlling method for fixing browsing image to
zoomed region of touch device of the embodiment according to the
present invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0020] Please refer to FIG. 1 to FIG. 6, FIG. 1 is a flowchart of
the controlling method for locking zoomed region, FIG. 2 to FIG. 6
are operating schematic diagrams of the controlling method for
fixing browsing image to zoomed region of touch device.
[0021] A controlling method for fixing a scale ratio of browsing
images of a touch device according to the present invention is
applied to control a displaying region of a browsing image on a
touch device 1. The touch device 1 includes a tablet computer, a
smart phone, or any electronic devices with touch function. In this
embodiment, the touch device 1 is exampled as a tablet computer and
a method of controlling the operation of zooming in is described in
FIG. 2 to FIG. 6.
[0022] A program, which performs the controlling method for fixing
a scale ratio of browsing images of a touch device according to the
present invention is built and executed in the touch device 1.
First, in FIG. 3, a user touches the display screen 11 of the touch
device 1. The fingers of a user start their movement from a
position 121 of a browsing image 12 on a display screen 11, which
is the page 1 of 16, in this embodiment, and extend outward to
enlarge the scale ratio of zooming. Accordingly, a zoomed region
12'' is formed, and the scale ratio is thus determined. (Step S1).
In other words, a user uses finger ends to touch the display screen
11 of the touch device 1 from the position of U1 and U2
respectively, and drag outward to enlarge the browsing page 12 with
a specific scale ratio of zooming, and thus a zoomed region 12'' is
formed. The image covered by the zoomed region 12'' is displayed on
the display screen 11 as shown in FIG. 4.
[0023] Next, in FIG. 4, a screen-locking icon F that is activated
to lock the scale ratio of zooming, referring to the screen-locking
function, is shown on the display screen 11. The scale ratio of
zooming is locked when the screen-locking icon F is touched (Step
S2). In other words, all contents of the zoomed region 12'', which
is letters of H, I, J and K, are fully displayed on the display
screen 11, and at the same time the scale ratio of zooming is also
fixed. The further zooming operation will be performed according to
the fixed scale ratio of zooming (Step S3). In Step S4, the user is
allowed to further adjust the scale ratio of zooming by touching
the display screen 11 and changing the zoomed region 12'' to
determine another scale ratio of zooming.
[0024] No matter the step S4 is performed or not, when the other
browsing images such as the page 2 of 16 in this embodiment are
viewed, a user views this browsing images with the same size as the
zoomed region 12'', which is referred to a zoomed region 12'''' in
FIG. 5, whose scale ratio of zooming is maintained (Step S5). In
other words, as shown in FIG. 5, the scale ratio and the scope size
of the letters of 1, 2, 3 and 4 shown in the zoomed region 12''''
is the same as these of zoomed region 12'' with letters of H, I, J
and K. That is, the other browsing images are viewed with the same
scale ratio of zooming and with a viewing size same as the zoomed
region 12''.
[0025] Then, as shown in FIG. 5, the scale ratio of zooming is
restored to the original one when the user triggers the
screen-locking F again, which is now referring to as a unlocking
state. Thereafter the browsing image will be view with the restored
original scale ratio of zooming at the same time (Step S6).
[0026] It is noted that the control method for zooming out is
similar to the above control method for zooming in as described in
FIG. 2 to FIG. 6. Similarly, a user touches the display screen 11
of the touch device 1. The fingers of a user start their movement
from a position 121 of a browsing image 12, and move inward to
minify the scale ratio of zooming. Accordingly, a zoomed region
12'' is formed, and the scale ratio is thus determined. (Step S1).
In other words, a user uses finger ends to touch the display screen
11 of the touch device 1 from the position of U1 and U2
respectively, and drag inward to minify the browsing page 12 with a
specific scale ratio of zooming, and thus a zoomed region 12'' is
formed. The image covered by the zoomed region 12'' is displayed on
the display screen 11 as shown in FIG. 4.
[0027] Next, in FIG. 4, a screen-locking icon F that is activated
to lock the scale ratio of zooming, referring to the screen-locking
function, is shown on the display screen 11. The scale ratio of
zooming is locked when the screen-locking icon F is touched (Step
S2). In other words, all contents of the zoomed region 12'', which
is letters of H, I, J and K, are fully displayed on the display
screen 11, and at the same time the scale ratio of zooming is also
fixed. The further zooming operation will be performed according to
the fixed scale ratio of zooming (Step S3). In Step S4, the user is
allowed to further adjust the scale ratio of zooming by touching
the display screen 11 and changing the zoomed region 12'' to
determine another scale ratio of zooming.
[0028] No matter the Step S4 is performed or not, when the other
browsing images such as the page 2 of 16 in this embodiment are
viewed, a user views this browsing images with the same size as the
zoomed region 12'', which is referred to a zoomed region 12'''' in
FIG. 5, whose scale ratio of zooming is maintained (Step S5). In
other words, as shown in FIG. 5, the scale ratio and the scope size
of the letters of 1, 2, 3 and 4 shown in the zoomed region 12''''
is the same as these of zoomed region 12'' with letters of H, I, J
and K. That is, the other browsing images are viewed with the same
scale ratio of zooming and with a viewing size same as the zoomed
region 12''.
[0029] Then, as shown in FIG. 5, the scale ratio of zooming is
restored to the original one when the user triggers the
screen-locking F again, which is now referring to as a unlocking
state. Thereafter the browsing image will be view with the restored
original scale ratio of zooming at the same time (Step S6).
[0030] One skilled in the art will appreciate that the browsing
image on the touch device contains one or more members selected
from the group including text, graph, symbol, and video and the
present invention is not limited by the embodiment as shown in FIG.
2 to FIG. 6, although the preferred embodiment of the present
invention has been described.
[0031] As can be appreciated from the above embodiments, the
controlling method for fixing a scale ratio of browsing images of a
touch device of the present invention has merits which meet the
requirement for a patent. The above description should be
considered as only the discussion of the preferred embodiments of
the present invention. However, a person skilled in the art may
make various modifications to the present invention. Those
modifications still fall within the spirit and scope defined by the
appended claims.
